1 . Calculate the number of moles of H+ and OH- initially present the number of moles of h2O produced in the response regulation reaction.

2. For more precise heat of reaction measurements chemists use a device called a bomb calorimeter . how is a bomb calorimeter similar to and different from a polystyrene cup calorimeter ? cite your reference .

3. Consider the temperature change, together with the volume and concentration of the acid and base, noted in the HAZMAT team's response regulation information. Predict how each of the following variations would affect the observed temperature change. Explain your predictions.

(a) using 100 mL 1M hydrochloric acid and 100mL 1M sodium hydroxide

(b) using 50 mL 2M hydrochloric acid and 50 mL 2M sodium hydroxide

(c) using 25 mL 1M hydrochloric acid and 75 mL 1M sodium hydroxide

(d) using 25 mL 1M sulfuric acid and 75 mL 1M sodium hydroxide
